Oracle 11带来的安全加固:透明网关实现
随着网络技术的发展,数据库的安全问题越来越受到关注。Oracle 11带来的新特性透明网关(Transparent Gateway)为数据库安全带来了更加全面的加固。
透明网关是Oracle 11推出的一种新型网关,它的主要作用是连接不同类型的数据库。例如,它可以连接Oracle数据库和MySQL数据库,进行数据的传输和共享。通过透明网关,我们就可以实现不同数据库之间的互通,使得数据共享和协作变得更加方便和高效。
在实现数据共享的同时,透明网关也为我们的数据库安全带来了更加全面的保障。具体来说,它有以下几个方面的作用:
1. 数据加密
透明网关可以对数据进行加密,在传输过程中保障数据的安全性。具体来说,它采用了双重加密机制,既有SSL加密,又有IPSec加密,双重保障数据的安全性。
以下是透明网关中实现SSL加密的代码:
tnsnames.ora配置:
dgw = (DESCRIPTION =
(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = yourGatewayHost)(Port = 1521))
) (CONNECT_DATA =
(SID = dgw) (PRESENTATION = JAVASOLUTIONS)
(HS=OK) )
)
listener.ora配置:
LISTENER = (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = yourGatewayHost)(PORT = 1521)) )
SID_LIST_LISTENER = (SID_LIST =
(SID_DESC = (SID_NAME = dgw)
(ORACLE_HOME = yourOracleHome) (PROGRAM = dg4odbc)
(ENVS = LD_LIBRARY_PATH=/usr/X11/lib) )
)
sqlnet.ora配置:
SQLNET.AUTHENTICATION_SERVICES = (NONE)SQLNET.INBOUND_CONNECT_TIMEOUT = 180
gateway.ora配置:
HS_FDS_CONNECT_INFO = yourODBCConnectionString HS_FDS_TRACE_LEVEL = OFF
trace_level_client = OFF trace_level_server = OFF
# HS_FDS_SHAREABLE_NAME = /usr/odbc/lib/libmyodbc.so # HS_FDS_SHAREABLE_NAME = /usr/lib64/libodbc.so
# HS_FDS_SHAREABLE_NAME = /usr/local/easysoft/sqlserver/lib/libessqlsrv.so
dg4odbc.ora配置:
#Dg4ODBC Initialization file, need to be provided.#
#File name is dg4odbc.init
##Environment variables required for the ODBC Driver
#(required by OCI Gateway)#
[ENV]#For HP-UX and Solaris:
#LD_LIBRARY_PATH=/opt/odbc:/usr/X11/lib
##ODBC connection string for the SQL Server Database
#[ODBC]
Driver=
Server=
Database=
Uid=
Pwd=
2. 认证授权
透明网关可以实现对用户的认证授权管理。具体来说,我们可以在透明网关中配置连接信息和认证信息,使得只有经过认证授权的用户才能访问数据库。这样一来,我们就可以控制访问数据库的用户,防止未经授权的用户对数据库进行非法操作。
以下是透明网关中实现认证授权的代码:
tnsnames.ora配置:
dgw = (DESCRIPTION=
(CONNECT_DATA= (SID= dgw)
(PROGRAM=dg4odbc) (ENVS=LD_LIBRARY_PATH=/usr/X11/lib:$LD_LIBRARY_PATH)
) (ADDRESS=(PROTOCOL=tcp)(HOST=yourGatewayHost)(PORT=1521))
(CONNECT_TIMEOUT=40) )
listener.ora配置:
LISTENER = (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = yourGatewayHost)(PORT = 1521)) )
SID_LIST_LISTENER = (SID_LIST =
(SID_DESC = (SID_NAME = dgw)
(ORACLE_HOME = yourOracleHome) (PROGRAM = dg4odbc)
(ENVS = LD_LIBRARY_PATH=/usr/X11/lib) )
)
sqlnet.ora配置:
SQLNET.AUTHENTICATION_SERVICES = (NONE)SQLNET.INBOUND_CONNECT_TIMEOUT = 180
gateway.ora配置:
HS_FDS_CONNECT_INFO = yourODBCConnectionString HS_FDS_TRACE_LEVEL = OFF
trace_level_client = OFF trace_level_server = OFF
# HS_FDS_SHAREABLE_NAME = /usr/odbc/lib/libmyodbc.so # HS_FDS_SHAREABLE_NAME = /usr/lib64/libodbc.so
# HS_FDS_SHAREABLE_NAME = /usr/local/easysoft/sqlserver/lib/libessqlsrv.so
dg4odbc.ora配置:
#Dg4ODBC Initialization file, need to be provided.#
#File name is dg4odbc.init
##Environment variables required for the ODBC Driver
#(required by OCI Gateway)#
[ENV]#For HP-UX and Solaris:
#LD_LIBRARY_PATH=/opt/odbc:/usr/X11/lib
##ODBC connection string for the SQL Server Database
#[ODBC]
Driver=
Server=
Database=
Uid=
Pwd=
3. 可扩展性
透明网关还具有高度的可扩展性。它支持多种不同类型的数据库之间的连接,包括Oracle、MySQL、SQL Server等。这样一来,我们就可以实现多次数据共享,扩大了数据库的范围和应用场景。
综上所述,透明网关是Oracle 11带来的重要安全特性之一。它可以保障数据的安全性、进行认证授权管理,同时还具有高度的可扩展性,可以实现多次数据共享和扩大数据库的应用场景。在实际应用中,我们可以根据需要配置和使用透明网关,提高数据库的安全性和效率。
